Czech currency is the Czech Crown – CZK / Kč with exchange rate 1 EUR = 25.87 CZK (in September 2019). It is advisable to use the ATM or exchange money in banks rather than in the street exchange offices. We advise not to exchange money at the airport and never in the streets. For current exchange rates please check the Czech National Bank www.cnb.cz. The credit cards are widely accepted in shops and restaurants, which means you almost do not need cash. Also, euros is widely accepted, but beware that in such situations the rates are usually not very convenient.
